Read the general professional work overview
A Saint-Lazare applicant may need an employer’s explanation of work on a sensitive project. Identify the facts needed for the TN assessment and ask how they can be supported accurately, rather than replacing them with an empty title. A first review should produce a document map that separates facts the employer can state openly from facts that need a controlled description. It should identify the listed profession, actual duties, intended period, compensation, employer authority, and the applicant’s credential record. Hypothetical example: a water-quality engineer is assigned to a restricted industrial remediation project; the employer can explain the engineering analysis, reporting line, and deliverables without disclosing the client’s confidential formula. The decision is whether the available evidence describes the real professional arrangement, not whether the project can be made to sound secret.
Separate confidential detail from the actual role
The employer should explain the services, responsibilities, compensation and intended period. Hypothetical example: the project name is sensitive but the actual professional tasks can be described accurately. Do not invent technical duties or assume that a confidentiality label removes the need to establish the professional arrangement. Ask for a letter that uses accurate, non-sensitive language for the day-to-day work and identifies a person able to confirm it. Pair that letter with a limited project description, organizational context, and any authentic supporting records. Redaction should remove only what is genuinely sensitive; it should not leave the reviewer unable to tell what services the professional will provide.
Retain the individual qualification evidence
TN requires Canadian or Mexican citizenship and the prescribed qualifications for a listed profession. Experience is not a universal replacement for a required degree. Degrees from institutions outside Canada, Mexico or the United States require reliable foreign-credential evaluation. A general assurance from the employer does not evaluate the credential or resolve a profession mismatch. The credential decision should be made from the record that actually awards the degree, licence, or required alternative qualification. Collect transcripts, licences where relevant, translations, and a foreign evaluation when the rule calls for one. Do not wait until travel is imminent to discover that the job description and the qualification point to different professional categories.
Ask about the actual evidence and procedure
Identify what can be provided and what remains unresolved for the intended process. Do not assume every redaction will be accepted or alter an authentic record’s meaning. TN also prohibits services to a U.S. entity solely owned or controlled by the applicant. The final explanation needs to support the real work and ownership arrangement, not merely protect a preferred narrative. Sequence the review by confirming citizenship, professional category, qualifications, employment facts, and ownership before selecting the procedure. A Canadian citizen can seek TN classification through CBP on arrival or preclearance, while an employer can submit Form I-129 to USCIS in an appropriate case. The proposed service cannot be self-employment for an American enterprise the applicant owns or controls. Those records settle the choice more reliably than a polished but incomplete employer letter.
